To aZZ whom it may concern:

Beitknown that I, BRODERIOK HASKELL, of Franklin, in the county ofVenango and State of Pennsylvania, have invented a certain new anduseful Improvement in Bumping Posts for Railroads, of which improvementthe following is a specification.

My invention relates to devices for arresting the movement ofrailroad-vehicles at the end of a line of track, so as to prevent theiraccidental and undesired traverse beyond it; and its object is toprovide an appliance of such type which Will effectually resist and takeup the momentum of the moving vehicle or vehicles, which will preventthe vehicle which contacts with it from raising and passing over it, andwhich may be constructed at comparatively low cost and readily andsecurely installed in operative position.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings, Figure 1 is a side view in elevation of abumping-post, illustrating an application of my invention, a portion ofthe track-rail nearer the observer being broken away to show theconstruction more clearly; and Fig. 2, a front view of the same.

In the practice of my invention I provide a vertical post or support 1,which may be of timber, stone, or concrete and which is firmly bedded inthe ground adjacent to the blind or terminal end of a line oftrack-rails 2. A

bumper-head 3, which is preferably made of cast-steel or Wrought-ironand which is provided with two lateral arms 3, extending downwardly atan angle of forty-five degrees, or thereabout, from the front end of itsbase, is suppbrted through a suitable yielding resistance medium, whichin this instance is shown as a plurality of coiled springs 4: on the topof the post 1, the front face of the head standing normally at such alevel above the rails as to afford an abutment for the draw-head of anapproaching railroad-vehicle.

An outwardly-extending lip or projection 3 is formed at and adjoiningthe top of the front face of the bumper-head for the purpose of forcingthe draw-bar of a contacting car downwardly, and thereby preventing thecar frori rising and passing over the top of the hea The arms 3 of thebumper-head extend to or near the level of the track-rails and arepivoted by bolts 5 to the upper ends of astout metallic yoke 6, which issecurely anchored in the ground below the rails and in advance of thepost and is firmly held by a suitable fixed resistance medium, as byties, timbers, or slabs of stone or concrete 7 abutting against it atright angles to the central plane of its side arms and of the connectedarms of the bumper-head.

It will be obvious to those skilled in the art that, if desired,increased yielding resistance may be obtained by the employment offrictional devices to receive and take up the impact of a car strikingthe bumper-head, and a device of such character-as, for example, thewell-known Westinghouse friction draftgear-rnay be interposed betweenthe bumper head and post in lieu of the ordinary coiled springs hereindescribed and shown.

In the operation of the appliance the contact of a moving car with thefront face of the bumper head tends to move the head downwardlytowardthe post upon the connectingbolts 5 of the yoke as pivots, such downwardmovement being opposed by the 'springs or other yielding resistancemedium upon which the head is supported, which.

medium takes upthe momentum ofthe car and brings it to a stop withoutdamage to itself or to the appliance.

I claim as my invention and desire to secure by Letters Patent- 1. In arailroad bumping-post, the combination of a post or support, abumperhead located above said post and having downwardly-inclined arms,a yielding resistance medium interposed between the bumper head andpost, and a yoke anchored in advance of the post and coupled by flexibleconnections tothe arms of the bumper-head.

2. In a railroad bumping-post, the combination of a post or support, abumper-head located above said post and having downwardly-inclined arms,a yielding resistance medium interposed between the bumper head andpost, a yoke anchored in advance of the post and havingupwardly-extending arms, and pivot-bolts connecting said arms to thearms of the bumper-head.

3. In a railroad bumping-post, the combination of a post or support, abumper-head located above said post and having downwardly-inclined arms,an outwardly extending' lip or projection at the top of the front faceof the bumper-head, a yielding resistance medium interposed between thebumper head and post, and a yoke anchored in advance of the post andcoupled by flexible connections to the arms of the bumper-head.

4c. In a railroad bumping-post, the combination of a post or support, abumper-head located above said post and having down- Wardly-inclinedarms, a yielding resistance medium interposed between the bumper headand post, a yoke anchored in advance of the post and having a transversebody and arms extending," upwardly in the direction of the arms of thebumper-head, pivot-bolts connecting the arms of the yoke and thebumperhead, and a fixed resistance medium abutting against the body ofthe yoke.
